Condoms, usually made of latex but sometimes made of polyurethane or other materials, are classified as medical devices, so they must meet standards set by groups such as the International Organization for Standardization (ISO) and the American Society for Testing and Materials (ASTM). .
The ISO, for example, subjects condoms to “air burst” and “electrical” tests to make sure condoms don’t have holes and don’t break. ISO also mandates a thickness standard and sets requirements for the lifespan of condoms.
However, the most reported problem with condoms is their application. Up to 50% of men believe that the condoms they use don’t fit.
Men have reported other problems as well. Some say that the sex not so good when they wear one. Others complain of irritation, difficulty maintaining an erection, or that their condoms dry out during sex.
Is there a right size?
The average penis size is somewhere between 5 and 7 inches in length and 3.5 to 6 inches in circumference, although penis size varies.
When it comes to condom sizes, both ISO and ASTM set the minimum length for a condom at about 6.3 inches. Most are about 7 inches and many have extra room at one end of the “tank” to catch sperm.
